DETACHABLE SHOE HEEL Filed Feb. 25, 1963 FIG. 5.

\W\ \w\\- /////XV/ 15 I INVENTOR David J. Deifch United States Patent3,13as04 DETACPABLE SHOE HEEL David J. Deitch, 6 E. 7th St, Wilmington1, Del.; Bernard Deitch and Philip Qohen, executors of said David .3.Deiteh, decemed Filed Feb. 25, 1953, Ser. No. 251L671 4 (Ilaims. (*Cl.36-36) The instant invention relates to shoes, and more particularly toa detachable heel therefor, for replacement of a worn heel with a newone.

One of the primary objects of the invention is the provision of a heeldetachably secured to a shoe upper by means of mating plates andfasteners, one of the plates being attached to the rear portion of theshoe sole internally thereof and the other embedded in the heel.

Yet a further aim is the making of a detachable heel [for a shoe upperin which mating plates and separable fasteners are employed; and inwhich the arrangement is such that the fasteners are not subject towear; and in which separation or connection of the heel is made fromwithin the shoe.

A still further purpose is the making of a detachable heel for a shoeemploying mating plates and separable fasteners especially adapted foruse with the detachable sole of applicants Patent No. 3,073,042 issuedJanuary 15, 1963, although not by any means limited thereto.

The above and other aims and objects will be apparent from the detaileddescription hereinafiter appearing when taken in conjunction with theappended drawing forming a part hereof to which reference is now madeand in which:

FIG. 1 is a perspective view of a sole plate showing an attaching screw;

FIG. 2 is a side elevational exploded view showing the plate of FIG. 1in position in the shoe and a heel, having a mating plate, in attachingposition;

FIG. 3 is a bottom plan view of the rear portion of a shoe sole showingthe manner in which the sole plate is secured thereto;

FIG. 4 is an exploded perspective view showing how a plate is assembledfor sandwich molding within the heel;

1G. 5 is a view, on a larger scale, of the rear portion of a shoeshowing in section the separable heel in attached or wearing condition;and

FIG. 6 is a sectional view, also on a larger scale, showing a detail ofthe separable fastening means.

Referring more particularly to the drawings, and FIGS. 1, 2 and 3thereof, the reference character C designates the rear upper port-ion ofa conventional shoe such as may be worn by men, women and children, andF a unitary plate member secured interiorly of the rear upper shoeportion C in a manner now to be described. Turning first to the platemember F, it will be noted that it comprises an annular flat portion lilhaving a central opening 11 and a plurality of spaced, depending hollow,cylindrical sleeves l2. It will further be seen that plate member 'F iscomplementary in shape to the rear upper shoe portion, that is to say,also complementary in shape to the heel to be secured thereto; and whilethe plate may be made of thin metal, it is preferably cast as astructurally integral unit of a thermosetting resin The leather materialor the like of which rear upper shoe pontion C is formed is foldedinwardly as at 13, FIG. 3, to form a flanged edge which is provided witha series of apertures 14 corresponding in number to sleeves 12 andthrough which the latter project. Before assembly, the contactingsurfaces of the flange l3 and flat plate portion are coated with anadhesive so that upon drying there is a firm bond between inturnedleather flange 13 and the plate member F.

The detachable heel member H, shown in exploded view in FIG. 4-,comprises upper and lower heel sections 15 and 15a, respectively, ofrubber or the like, between which heel plate member M is sandwiched. Thelatter comprises an annular portion 16 defining an opening 17. Aplurality of spaced cylindrical sleeve members 18 project upwardly fromannular portion 13, each sleeve member 18 being internally threaded asat 19. Plate member M is complementary in shape to plate F, is similarlyformed as a structurally integral unit from a thermosetting resin and isheld by molding between heel portions 15 and 15a to be sandwichedtherein with sleeve members 18 protruding throu h openings 26 in theupper heel member 15. In FIG. 4, the heel H with plate M is shown priorto molding assembly and after assembly in the lower portion of FIG. 2.As will be noted, sleeves 18 of plate M are aligned with sleeves 12 ofplate F, each sleeve 13 being received within a sleeve 12 in male-femalerelationship.

The reference numeral 25, FIG. 5, designates the rear portion of thedetachable outer sole shown in applicants Patent 3,073,042 in thelowermost part of FIG. 1 thereof to the left of the dash line. This rearportion has a series of spaced openings 26 through which sleeves 12project, said portion 25 filling the space 27 shown in FIG. 6. An innersole is designated at 23, while reference numerals 2.9 and 3% indicate athreaded fastener and lock washer, respectively, for each internallythreaded sleeve 18.

The manner of attaching a heel member H to the rear upper shoe portion Cwill now be set out. The parts are aligned as in FIG. 2 and sleeves 18inserted into sleeves 12 with the latter inserted in apertures of solesection 25, that is apertures 25, as will be seen in FIG. 5. Inner solemember 28 is turned back and a detachable fastener comprising a screwand washer assembly 29 and Ell, is brought into threaded engagement withan internally threaded surface 19 of each sleeve 18 until all the partsare in tight abutting relationship, as in FIG. 5. Then the inner sole isturned back to cover the detachable fasteners, as shown, and the shoe isready to be worn. When it is desired to replace the heel, it is onlynecessary to reverse the above procedure.

By providing a separate plate member for both the rear portion of thesole and heel, a particularly rugged structure is attained. Furthermore,by having a series of interfitting sleeves spaced peripherally about theassembly, the heel is uniformly held in place at each section of theunion with the counter to form a rigid and longw-earing construction.

Having described my invention, what I claim is:

1. In a shoe having a sole including a heel portion and an upper, afirst plate interiorly of the shoe upper and secured to the heel portionof the sole, a plurality of spaced integral sleeves projectingdownwardly from the plate through said sole heel portion, a detachableheel having a second plate sandwiched therewithin, a plurality of spacedintegral sleeves projecting upwardly from said second plate through saiddetachable heel, said plates being complementary in shape and thesleeves of the respective plates being each in male-female relationship,and means for detachably holding said sleeves in said relationship.

2. The structure of claim 1, in which the means for securing the firstplate to the heel portion of the sole comprises an inturned flange ofthe shoe uppe said flange having a series of apertures through which thesleeves of the first plate downwardly project.

3. The structure of claim 2, and adhesive means binding said inturnedflange to said first plate.

4. The structure of claim 3, in which the upwardly projecting sleeves ofsaid second plate are internally threaded and in which said detachableholding means comprises screws threadedly engaging said last-mentionedsleeves.
